The AirTAC GC30010MLC2GK AirTAC F.R.L. Combination, G3/8, Low-Pressure is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT3/8" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30010MLC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator built as one coordinated set. It removes water and 40 um particulate from compressed air, regulates downstream pressure with the low-pressure type regulator, and adds oil-mist lubrication for downstream equipment. This configuration has a G3/8 (BSPP) port, a manual drain on the filter bowl, an external round gauge with a psi scale, a reverse/check valve fitted, and a mounting bracket included. The bowls on this size are polycarbonate (PC); only size 600 uses aluminium alloy.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and with drain, filter-grade, gauge, thread and valve options to match the circuit. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF300-10 filter, GR300-10 regulator and GL300-10 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

On a beverage bottling line, this F.R.L. set conditions the air feeding conveyor stoppers, lift cylinders and clamp actuators: water and grit are drained out, pressure is held at the low setting the actuators need, and a fine oil mist keeps cylinder seals working smoothly.
At a bench assembly station running impact drivers, nutrunners and air ratchets, the combination filters line dirt to 40 um, regulates the supply to the pressure the tools are set for, and lubricates the air so vane motors and triggers last longer.
Feeding the valve island and gripper circuit of a carton-packing machine, the set keeps condensate and particles out of the directional valves, holds a stable low regulated pressure for gentle gripper action, and the check valve helps hold the downstream circuit when upstream supply dips.
Size 300 with a G3/8 port is the mid step of the GC range; step up to size 400 or 600, or down to size 200, as the required flow and porting of your circuit dictate. The manual drain here means an operator opens the bowl drain periodically - choose the automatic or differential-pressure drain variant instead if the unit is mounted where routine draining is impractical. The 40 um grade is the standard element; a 5 um element (code W) is available when finer filtration is needed. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue choices. Thread is G (BSPP) on this unit; PT is the standard thread and NPT is also an order option. The low-pressure type regulator is intended for circuits that run below standard line pressure - its exact adjustment range is not published in the summary data, so confirm it with us. Flow is published as curves, not a single rating: ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a l/min, m3/h or SCFM figure here. Tell us your application and we will confirm the flow and the full datasheet figures for this exact model on request.
The M in the code specifies a manual drain on the filter bowl: an operator opens the drain periodically to expel collected water. If the unit will be mounted where routine draining is awkward, the same series is available with an automatic drain (code A) or the differential-pressure drain (no code) - ask us for those variants.
